RHESSI's upcoming anneal
by Shih, Albert Y. (GSFC-6710) 16 Jan '12

16 Jan '12

To RHESSI collaborators: As we prepare for RHESSI to enter its 11th year of operation, it is once again time to rejuvenate the detectors through an "anneal" procedure. RHESSI's germanium detectors degrade steadily over time due to radiation damage from charged particles, and heating up the germanium restores lost sensitivity and resolution. Starting on January 17 (UT), the detectors will be heated up from their operating temperature of ~100 K to ~100 deg C (373 K), held at that temperature for ten days, and then cooled back down. The entire procedure is anticipated to take about a month. During this time period, RHESSI will be unable to make X-ray and gamma-ray observations. If you have any questions about this upcoming anneal, please feel free to contact me. Albert Shih RHESSI Deputy Mission Scientist ————— Albert Y. Shih Solar Physics Laboratory, Code 671 NASA Goddard Space Flight Center Greenbelt, MD 20771 Office: 301-286-1843

Celebration of Bob Lin's 70th Birthday and RHESSI's 10th anniversary
by David Smith 06 Jan '12

06 Jan '12

Dear colleagues, My apologies if this reaches you multiple times through different channels. We will be having a celebration for Bob Lin's 70th birthday and the 10th anniversary of the launch of RHESSI, on Friday, Feb. 10th, in Berkeley. We will have RHESSI-related talks in the morning, a casual buffet lunch, and talks covering Bob's other science interests and personal reminiscences in the afternoon. There will be a banquet dinner at a local restaurant. Attendees will pay for lunch and dinner (probably on the order of $10 and $30, respectively), but there will be no other registration fee. We hope you can attend. RSVP by January 16th by going to the following link, entering your full name in the poll, and checking off which events you will attend as follows: http://www.doodle.com/22x2mubcq88c8iue 9AM means you will attend the morning talks 12PM means you will attend the buffet lunch 1PM means you will attend the afternoon talks 6:30PM means you will attend the banquet dinner We hope to see you there! -David Smith for the organizers
